Constructing Data Displays -Dot Plots (5)

Construct displays, including column graphs, dot plots and tables, appropriate for data type, with and without the use of digital technologies (ACMSP119)

LO: To construct data displays to collect data.

Know:

  • How to construct a data display
  • The different types of data displays

Understand:

  • That different types of data displays can be constructed to represent data.

Do:

  • I can construct data displays.

Data Tables

One way to collect data is to collect it in a data table.

Data collectors usually use tally tables to collect information.

To make it easier to read, usually data collectors use a cross tick for every fifth tally.

Column Graphs

This is a side column graph.

Column graphs use bars to represent data.

PictoGraphs

Data can also be represented using Pictographs.

Pictographs use pictures to represent information.

Sometimes each picture doesn’t have to represent 1 item. In this case each paw print represents 2 votes. So there are 8 votes for cats, 4 votes for dogs and 6 votes for hamsters.

Dot Plots

Dot plots are similar to pictographs but using dots instead of pictures to represent data.
